Aluminum profiles refer to aluminum alloy extrusions, but for those new to the industry, there is a common misconception: while aluminum profiles are often called aluminum alloy profiles, they are not actually made of aluminum alloy.
Aluminum profiles refer to aluminum alloy extrusions, yet newcomers to the industry often hold a significant misconception about this. Aluminum profiles are frequently called aluminum alloy profiles, but they are not the alloy itself. Simply put, the key distinction between aluminum alloy and aluminum profiles is that the former is a raw material, whereas the latter is a finished product that has undergone processing and can be used directly.
The earliest understanding of the aluminum profile forming process is that, by subjecting aluminum ingots or billets to three major steps—melting and casting, extrusion, and surface treatment—one can produce aluminum profiles with a wide variety of cross-sectional shapes. Both aluminum ingots and billets serve as raw materials; their typical lengths are 8 meters or 12 meters, and their diameters are generally available in four standard sizes: D90 mm, D105 mm, D120 mm, and D178 mm. Among these, the 6063 alloy is the most commonly used grade in China.
1. Melting and casting is the first step in aluminum production, primarily comprising key processes such as batching, melting, and casting.
2. Extrusion is a method for shaping profiles: first, a die is fabricated based on the desired cross-sectional geometry, and then a heated round billet is forced through the die.
3. Surface treatment involves processing the profile’s surface; common methods include anodizing, which can produce a sandblasted texture, a bright white finish, and oxidized coloration.
Industrial aluminum profiles
Finished aluminum profiles can be categorized into two types: one is architectural aluminum profile, primarily used in everyday applications such as aluminum alloy doors and windows, aluminum curtain walls, and other products commonly found in our daily lives; the other is industrial aluminum profile, mainly employed in industrial production and manufacturing—for example, in the frames of automated machinery and protective enclosures, as well as custom‑made molds tailored to specific equipment needs, such as conveyor belts, elevators, dispensing machines, inspection devices, and shelving units. These are widely utilized in the electronics and mechanical industries, cleanroom environments, and related fields.

Let us introduce you to what aluminum tubing is.
Aluminum tubing typically refers to pipes made from aluminum alloys. Aluminum alloys are materials composed of aluminum combined with other metallic elements, characterized by their light weight, high strength, and excellent corrosion resistance, making them widely used across various industries.
Aluminum tubes are mainly classified into the following types.
Classified by precision: ordinary aluminum tubes and precision aluminum tubes; the latter typically undergo secondary processes such as cold drawing and rolling after extrusion.
With the rapid growth of the new‑energy vehicle industry, automotive thermal management systems are confronting entirely new challenges and opportunities. In this field, aluminum tubing, thanks to its superior performance and broad range of applications, has steadily emerged as an unsung leader in thermal management for new‑energy vehicles, providing robust support for enhanced vehicle performance and safe operation.
Production and Manufacturing of Aluminum Tubes
Aluminum tubes are classified into four main types based on their forming process: hot-extruded aluminum tubes (the mainstream), cold-drawn and precision-rolled aluminum tubes, welded aluminum tubes, and impact-extruded pharmaceutical aluminum tubes. Among these, the most widely used in the industry is seamless or split‑die extruded aluminum tubing.
What is the difference between 409 stainless steel and 430 stainless steel?
Compared with ordinary low‑carbon steel, 409 stainless steel sheet exhibits poorer thermal conductivity and lower elongation; consequently, greater deformation forces are required during shearing and bending. For 321 stainless steel sheet, springback during bending is more pronounced than in carbon steel. Moreover, since the elongation of stainless steel sheet is lower than that of carbon steel, the bend radius R of the workpiece should be larger than that for carbon steel during bending operations; otherwise, cracking is likely to occur.
What is the difference between 202 stainless steel and 304 stainless steel?
202 stainless steel and 304 stainless steel are both austenitic stainless steels at their core, non-magnetic, and visually quite similar. However, the key difference lies in their nickel content, which results in significant variations in their mechanical properties and price.
